This may not be large enough but the "wind tube" made me think of it. Al you
need is a paper towel roll and soap bubble solution. Get a group of kids and
ask them to dip one end of the tube in the bubble solution and blow the biggest
bubble possible. (They will almost always put the tube right up to their
mouths)- then choose the littlest in the group, have him hold the tube about 4"
from his/her mouth and blow-same Bernoulli effect pulls a lot of air in to make
a gigantic bubble.
